exofs: address_space_operations
OK Now we start to read and write from osd-objects. We try to collect at most contiguous pages as possible in a single write/read. The first page index is the object's offset. TODO: In 64-bit a single bio can carry at most 128 pages. Add support of chaining multiple bios Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
